a single stage split

[ranlin]

Первый абзац инструкции по эксплуатации некоего нагревателя.

The elements in the heater can be wired for a number of control requirements. The wiring configuration should be marked on the terminal enclosure label. The use of any other connection configuration should only be done with the companies’ approval. The stage which is the first on and last off, should have the control attached to it. A zone configuration is a single stage split for multi-cable inputs. The advantage of this is, if one cable fails then the current load would not be passed to the other cables. The controls would see a multi-zone as a single stage.

2. The controls would see a multi-zone as a single stage.
Опять таки: как это по-русски?
